king007: I have added this change from upstream as a patch, which should fix this.

Problem Python 3.7 support in GNS3 already solved by Jeremy Grossman ( You can use GNS3 version 2.1.10dev2 to run GNS3 well in Arch Linux.. I already test it and it can run my topology network test with well..

You can download gns3-server package from here ( and gns3-gui package from here (

That version can be temporary solution until GNS3 2.1.10 final version has release and ready in aur..

@stonyboy So, does this mean we cannot install Gns3-Server for now ? Or is there any way to workaround ? Thank you in advance

The python version has been updated from 3.6 to 3.7 and the gns3 packages need to be bytecompiled again with the new python version.

If you like me are using a AUR package manager (e.g aurman) you need to remove the cached packages to be able to force this step (e.g remove the folders named ~/.cache/aurman/gns3* and the dependency python packages like python-aiohttp-cors-gns3 etc.)

Getting that far you will probably see a number of bytecompilation errors in the gns3-server package like this:

File "/usr/lib/python3.7/site-packages/gns3server/controller/", line 890 asyncio.async(self.start_all())

which signifies that the asyncio module has finally removed the asyncio.async function in favor of the asyncio.ensure_future function. The asyncio.async function was deprecated some python releases ago according to the documentation.

I have not yet checked with the GNS3 project site - but they will need to comply with this change - or the gns3-server package will need to contain a patch step for this to work with python 3.7

I ran into a dependency error. Seems to work with python-yarl-gns3 from aur instead of python-yarl.

vboxwrapper is no longer needed since 1.2.3 ( Would you mind removing it from the optional dependencies please?

predmijat commented on 2017-12-14 17:35

:: python-aiohttp-gns3 and python-aiohttp-135 are in conflict (python-aiohttp). Remove python-aiohttp-135? [y/N] y error: failed to prepare transaction (could not satisfy dependencies)

Anyone else?

I can confirm it's ok now. Thanks.
